利用svd的一种水印方法。SVD即奇异值分解(Singular Value Decomposition)算法。 -A watermarking method using svd. Singular value decomposition SVD that (Singular Value Decomposition) algorithm.

本程序可以实现对图像用Matlab进行奇异值分解-This program enables the images to use Matlab the singular value decomposition

运用奇异值分解，离散傅里叶变换的水印算法，完整程序-wartermarking algorithm

基于小波变换-奇异值分解的数字水印嵌入和提取，嵌入后的图像经过攻击后提取出来的相关系数可达到95 以上。-Based on wavelet transform- the correlation coefficient singular value decomposition digital watermark embedding and extraction, image-embedded extracted after the attack can reach more than 95 .

基于奇异值分解的水印检测算法，代码简单，容易，运行速度快。-Watermarking detection algorithm based on singular value decomposition, the code is simple, easy and fast.
